If the V bit is consistently high, to indicate continuous error states, or to indicate non
audio data, then the processor will give a silent output. All other cards, except RS4, pass
audio data unaltered even when V bit is set or held high.
Link jumpers are provided to select between 110 Ohm (upper 2 pins), HiZ (balanced –
centre pins only) or 75 Ohm (unbalanced – lower 2 pins). Jumper JL3 must be in the
TANDEM position.
Notes:
Balanced outputs require the use of rear modules with a ‘D’ type connector and
unbalanced outputs are for use with BNCs.
HiZ is achieved by removing termination jumpers – they can be parked for safe keeping
by replacing them using only one pin.
HD-AOP2
The analogue audio output module provides two stereo pairs or four mono outputs that may be
used as destinations when routing de-embedded signals. Link jumpers are provided to allow
0dBFS to be set to +18dBu or +24 dBu. The variable adjustments on the card are set at the
factory and should not require re-adjustment. Set channel 1 with PL1/P1, channel 2 with
PL2/P2, channel 3 with PL3/P3 and channel 4 with PL4/P4.
HD-AOP2
Selectable jumper links are provided to change input and reference terminations and pre-set
levels, depending on sub-module features.
